However, if and when Muslims do happen to form a state of their own, Islam does impose certain religious obligations on its rulers as establishment of the institutions of salat (obligatory prayer), zakah (mandatory charity), and 'amr bi'l-ma'ruf wa nahi 'ani'l-munkar (preservation and promotion of society's good conventions and customs and eradication of social vices); this, in Ghamidi's opinion, should be done in modern times through courts, police, etc. in accordance with the law of the land which, as the government itself, must be based on the opinion of the majority.
